Hi Experts,

while creating custom IDOC we need to create a FM i.e., (Posting program) which is used to fetch the data from IDOC and post the data into DB.

there we need to call 3 FM's

'EDI_DOCUMENT_OPEN_FOR_EDIT'

'EDI_CHANGE_DATA_SEGMENTS'

'EDI_DOCUMENT_CLOSE_EDIT'

plz explain why these FM are required and wht each does????

pts will b rewarded for correct answers

Hi,

EDI_DOCUMENT_OPEN_FOR_EDIT (unlocks the idoc for editing)

EDI_CHANGE_DATA_SEGMENT (writes any changes to the idoc segment)

EDI_DOCUMENT_CLOSE_EDIT (closes the idoc to editing)


Updating IDoc data in segments 
STEP 1 - Open document to edit 

CALL FUNCTION 'EDI_DOCUMENT_OPEN_FOR_EDIT' 

       EXPORTING 

            document_number               = t_docnum 
            IMPORTING 
            idoc_control                  = itab_edidc 
            TABLES 
            idoc_data                     = itab_edidd 

       EXCEPTIONS 

            document_foreign_lock         = 1 
            document_not_exist            = 2 
            document_not_open             = 3 
            status_is_unable_for_changing = 4 
            OTHERS                        = 5. 

STEP 2 - Loop at itab_edidd and change data

LOOP AT itab_edidd WHERE segnam = 'E1EDKA1'. 

  e1edka1 = itab_edidd-sdata. 

  IF e1edka1-parvw = 'LF'. 

    e1edka1-partn = t_eikto. 

    itab_edidd-sdata = e1edka1. 

    MODIFY itab_edidd.

    EXIT.

  ENDIF.

ENDLOOP. 

STEP 3 - Change data segments

CALL FUNCTION 'EDI_CHANGE_DATA_SEGMENTS' 

           TABLES 

                idoc_changed_data_range = itab_edidd 

           EXCEPTIONS 

                idoc_not_open           = 1 

                data_record_not_exist   = 2 

                OTHERS                  = 3.

STEP 3a - Change control record

CALL FUNCTION 'EDI_CHANGE_CONTROL_RECORD' 

       EXPORTING 

            idoc_changed_control         = itab_edidc 

       EXCEPTIONS 

            idoc_not_open                = 1 

            direction_change_not_allowed = 2 

            OTHERS                       = 3. 

STEP 4 - Close Idoc

* Update IDoc status

CLEAR t_itab_edids40. 

  t_itab_edids40-docnum      = t_docnum. 

  t_itab_edids40-status      = '51'. 

  t_itab_edids40-repid       = sy-repid. 

  t_itab_edids40-tabnam      = 'EDI_DS'. 

  t_itab_edids40-mandt       = sy-mandt. 

  t_itab_edids40-stamqu      = 'SAP'. 

  t_itab_edids40-stamid      = 'B1'. 

  t_itab_edids40-stamno      = '999'. 

  t_itab_edids40-stapa1      = 'Sold to changed to '. 

  t_itab_edids40-stapa2      = t_new_kunnr. 

  t_itab_edids40-logdat      = sy-datum. 

  t_itab_edids40-logtim      = sy-uzeit. 

  APPEND t_itab_edids40. 

  

  CALL FUNCTION 'EDI_DOCUMENT_CLOSE_EDIT' 

       EXPORTING 

            document_number  = t_docnum 

            do_commit        = 'X' 

            do_update        = 'X' 

            write_all_status = 'X' 

       TABLES 

            status_records   = t_itab_edids40 

       EXCEPTIONS 

            idoc_not_open    = 1 

            db_error         = 2 

            OTHERS           = 3.

Reward points if useful....

Hi,

read the IDOC data using the FM IDOC_READ_COMPLETELY, and find the errors

then now modify the IDoc using

EDI_DOCUMENT_OPEN_FOR_EDIT "open idoc

EDI_CHANGE_DATA_SEGMENTS "change the data

EDI_DOCUMENT_CLOSE_EDIT "close the IDOC

now change the status of the IDoc

The example codes can be found in website
